Description
本發明係關於一種液晶顯示面板,尤指一種可有效縮短響應時間(response time)之液晶顯示面板。The present invention relates to a liquid crystal display panel, and more particularly to a liquid crystal display panel which can effectively shorten the response time.
隨著液晶顯示技術不斷的提升,液晶顯示面板已廣泛地被應用在平面電視、筆記型電腦、智慧型手機與各類型的消費型電子產品上。為了解決習知液晶顯示面板之視角過窄的缺點,業界研發出一種邊緣電場切換型(fringe field switching, FFS)液晶顯示面板,其主要特色在於將共同電極與畫素電極設置於陣列基板(亦稱為薄膜電晶體基板)的不同平面上,並藉由共同電極與畫素電極之間的電壓差產生的電場達到廣視角的規格。With the continuous improvement of liquid crystal display technology, liquid crystal display panels have been widely used in flat-panel televisions, notebook computers, smart phones and various types of consumer electronic products. In order to solve the disadvantage that the viewing angle of the conventional liquid crystal display panel is too narrow, a fringe field switching (FFS) liquid crystal display panel has been developed in the industry, and the main feature is that the common electrode and the pixel electrode are disposed on the array substrate (also The electric field generated by the voltage difference between the common electrode and the pixel electrode reaches a wide viewing angle in different planes called a thin film transistor substrate.
在習知邊緣電場切換型液晶顯示面板中,響應時間(response time)為影響畫面品質的重要決定因素。一般來說,響應時間可分為兩個部分,一為上升(raising)時間,另一為下降(falling)時間,且響應時間則為上升時間與下降時間之和。在上升時間中,液晶分子受共同電極與畫素電極之間的電場影響而轉動,因此上升時間容易受到控制,目前發展出多種用以縮短上升時間的方法,然而下降時間則仰賴液晶分子間的彈性作用力回復而不易被控制。目前仍無有效縮短下降時間的方法,以更進一步縮短液晶顯示面板的響應時間。In the conventional edge electric field switching type liquid crystal display panel, the response time is an important determinant that affects the picture quality. In general, the response time can be divided into two parts, one is the raising time, the other is the falling time, and the response time is the sum of the rising time and the falling time. In the rise time, the liquid crystal molecules are rotated by the electric field between the common electrode and the pixel electrode, so the rise time is easily controlled, and various methods for shortening the rise time have been developed, but the fall time depends on the liquid crystal molecules. The elastic force is restored and not easily controlled. At present, there is still no effective method for shortening the fall time to further shorten the response time of the liquid crystal display panel.

Please refer to FIG. 5 and refer to FIG. 2 and FIG. 3 together. FIG. 5 illustrates the first voltage of the liquid crystal display panel of the first embodiment of the present invention. A timing diagram of the difference V 1 and the second voltage difference V 2 . As FIGS. 2 through FIG. 3 and 5 shown in the display period T1, providing at least a first voltage difference V 1 to at least a pixel electrode 106 and the common electrode 112, to generate a second direction of The electric field further drives the long axis of the positive liquid crystal molecules to turn in the second direction to turn on the corresponding pixels and display the picture. Further, in the display period T1, there is no voltage difference between the first strip electrode 108 and the second strip electrode 110. Specifically, the pixel electrode 106 provides a pixel signal, the common electrode 112 provides a common signal, the first strip electrode provides a first voltage signal, and the second strip electrode provides a second voltage signal. In the display period T1, the voltage difference between the pixel signal and the common signal is the first voltage difference V 1 , and the voltages of the first voltage signal and the second voltage signal are the same as the voltage of the common signal. In the off period T2, for example, when the screen display ends or the pixel needs to be switched to the dark state, the first voltage difference V 1 can be reduced to less than 0.5 volts, and the first voltage signal and the second voltage signal are respectively provided differently. The voltage is applied to the first strip electrode 108 and the second strip electrode 110 such that the at least one first strip electrode 108 and the at least one second strip electrode 110 have a second voltage difference V 2 , or any two phases A second voltage difference V 2 is present between the adjacent first strip electrode 108 and the second strip electrode 110, wherein the duration of providing the second voltage difference V 2 is from 1 to 10 milliseconds, preferably from 5 to 10 milliseconds. In the off period T2, the voltage difference between the first voltage signal and the second voltage signal is the second voltage difference V 2 . At this time, the first strip electrode 108 and the second strip electrode 110 generate an electric field perpendicular to the second direction. In this embodiment, the electric field direction is the first direction to assist and accelerate the return of the long axis of the positive liquid crystal molecules to The initial position, which is parallel to the first direction. Therefore, the liquid crystal display panel 1A of the present embodiment can effectively shorten the fall time by effectively providing the first strip electrode 108 and the second strip electrode 110 which are not parallel to the extending direction of the pixel electrode 106, thereby effectively shortening the liquid crystal display panel. 1A response time. In addition, in the display period T1, the voltages of the first strip electrode 108, the second strip electrode 110, and the common electrode 112 may be the same, and in the off period T2, the second voltage difference V 2 is preferably Between 5 volts and 30 volts, more preferably between 8 volts and 15 volts, but not limited to this.

In order to clearly show the main spirit of the embodiment of the present variation, the common electrode is not shown in FIG. As shown in FIG. 6, the present variation is different from the first embodiment in that the first direction in which the pixel electrode 106 and the slit S extend is not the vertical direction Y, and the first direction and the first strip electrode 108 are The second direction (ie, the horizontal direction X) in which the second strip electrode 110 extends has an acute angle, and the angle of the angle is 85 to 90 degrees, but is not limited thereto. In other variant embodiments, the angle of the included angle may vary, and may range from substantially 70 to 90 degrees, preferably from 80 to 90 degrees, and more preferably 90 degrees. On the other hand, the extending direction of the first strip electrode 108 and the second strip electrode 110 in the modified embodiment is parallel to the extending direction of the first gate line GL1, but is not limited thereto. In other variant embodiments, the extending direction of the first strip electrode 108 or the second strip electrode 110 may not be parallel to the extending direction of the first gate line GL1, such as the first strip electrode 108 or the second strip electrode. The extending direction of the 110 may have an acute angle with the extending direction of the first gate line GL1, and the acute angle may be less than 10 degrees. Moreover, the present modified embodiment can also be applied to other embodiments.
請參考第7圖,其繪示了本發明之第一實施例之第一變化實施例之液晶顯示面板之條狀電極之寬度與間隙之比值與下降時間的關係圖。在本變化實施例中,液晶顯示面板1B之液晶層104包括正型液晶分子,且液晶顯示面板1B的驅動方法可與第一實施例相同,在此不再贅述。如第7圖所示,STD代表習知未設置條狀電極之液晶顯示面板,並具有第一條狀電極108與第二條狀電極110之液晶顯示面板與STD做比較,其中以STD之下降時間作為基準,另外六組具有第一條狀電極108與第二條狀電極110之液晶顯示面板之第二電壓差V 2皆為20伏特,且第一條狀電極108與第二條狀電極110之寬度W與間距D皆符合公式(1)。然而,當第二電壓差V 2小於5伏特時,效果不佳,幾乎無功效,另外,目前系統無法供應大於30伏特的第二電壓差V 2,因此,在符合公式(1)的情況下效果較佳。由第7圖可知,本實施例於液晶顯示面板1B之第二基板102設置第一條狀電極108與第二條狀電極110可有效降低液晶顯示面板1B之下降時間,進而可有效降低響應時間,以提升顯示的品質。 Referring to FIG. 7, there is shown a relationship between the ratio of the width and the gap of the strip electrodes of the liquid crystal display panel of the first modified embodiment of the first embodiment of the present invention to the fall time. In the present embodiment, the liquid crystal layer 104 of the liquid crystal display panel 1B includes positive liquid crystal molecules, and the driving method of the liquid crystal display panel 1B can be the same as that of the first embodiment, and details are not described herein again. As shown in FIG. 7, the STD represents a liquid crystal display panel in which a strip electrode is not provided, and the liquid crystal display panel having the first strip electrode 108 and the second strip electrode 110 is compared with the STD, wherein the STD is decreased. The second voltage difference V 2 of the liquid crystal display panel having the first strip electrode 108 and the second strip electrode 110 is 20 volts, and the first strip electrode 108 and the second strip electrode are used as a reference. The width W and the spacing D of 110 are in accordance with the formula (1). However, when the second voltage difference V 2 is less than 5 volts, the effect is poor and almost no effect. In addition, the current system cannot supply the second voltage difference V 2 greater than 30 volts, and therefore, in the case of conforming to the formula (1) The effect is better.

請參考第8圖,其繪示了本發明之第一實施例之第二變化實施例之液晶顯示面板之條狀電極之寬度與間隙之比值與下降時間的關係圖。本變化實施例與第一實施例不同之處在於,液晶顯示面板之液晶層104以負型液晶分子為例,也就是說液晶分子的介電異方性小於0。以第1圖之液晶顯示面板1A的結構為例,並且,液晶層104的配向方向以平行水平方向X為例,使負型液晶分子的長軸可平行水平方向X,但不以此為限。在顯示時段T1中,可提供第一電壓差V 1至畫素電極106與共同電極112之間,以產生垂直第一方向之電場,進一步驅動負型液晶分子之長軸朝第一方向(即垂直方向Y)轉向,以顯示出畫面。在關閉時段T2中,可將第一電壓差V 1降為小於0.5伏特,並且提供第二電壓差V 2至第一條狀電極108與第二條狀電極110之間,以使得第一條狀電極108以及第二條狀電極110之間產生垂直第二方向之電場,以輔助且加速負型液晶分子之長軸回復至初始的位置,也就是平行水平方向X。如第8圖所示,STD代表習知未設置條狀電極之液晶顯示面板,並與具有第一條狀電極108與第二條狀電極110之液晶顯示面板與STD做比較,其中以STD之下降時間作為基準,另外具有第一條狀電極108與第二條狀電極110之液晶顯示面板之第二電壓差V 2皆為20伏特,且第一條狀電極108與第二條狀電極110之寬度W與間距D皆符合公式(1)。由第8圖可知,本實施例於液晶顯示面板之第二基板102設置第一條狀電極108與第二條狀電極110,確實可有效降低液晶顯示面板之下降時間,進而可有效降低響應時間,以提升顯示的品質。此外,本變化實施例亦可應用於其他實施例。 Referring to FIG. 8, there is shown a relationship between the ratio of the width and the gap of the strip electrodes of the liquid crystal display panel of the second modified embodiment of the first embodiment of the present invention to the fall time. The present variation is different from the first embodiment in that the liquid crystal layer 104 of the liquid crystal display panel is exemplified by negative liquid crystal molecules, that is, the dielectric anisotropy of the liquid crystal molecules is less than zero. Taking the structure of the liquid crystal display panel 1A of FIG. 1 as an example, and the alignment direction of the liquid crystal layer 104 is taken as an example in the parallel horizontal direction X, the long axis of the negative liquid crystal molecules may be parallel to the horizontal direction X, but not limited thereto. . In the display period T1, a first voltage difference V 1 may be supplied between the pixel electrode 106 and the common electrode 112 to generate an electric field in a first direction perpendicular to the first direction, further driving the long axis of the negative liquid crystal molecule toward the first direction (ie, Steer in the vertical direction Y) to display the picture. In the off period T2, the first voltage difference V 1 may be reduced to less than 0.5 volts, and the second voltage difference V 2 is supplied between the first strip electrode 108 and the second strip electrode 110 such that the first strip An electric field perpendicular to the second direction is generated between the electrode 108 and the second strip electrode 110 to assist and accelerate the return of the long axis of the negative liquid crystal molecules to the initial position, that is, the parallel horizontal direction X. As shown in FIG. 8, the STD represents a conventional liquid crystal display panel in which strip electrodes are not provided, and is compared with an STD having a first strip electrode 108 and a second strip electrode 110, wherein STD is used. The second voltage difference V 2 of the liquid crystal display panel having the first strip electrode 108 and the second strip electrode 110 is 20 volts, and the first strip electrode 108 and the second strip electrode 110 are used as a reference. The width W and the spacing D all conform to the formula (1). It can be seen from FIG. 8 that the first strip electrode 108 and the second strip electrode 110 are disposed on the second substrate 102 of the liquid crystal display panel, which can effectively reduce the falling time of the liquid crystal display panel, thereby effectively reducing the response time. To improve the quality of the display. Moreover, the present modified embodiment can also be applied to other embodiments.
